Peptide Comparison

LivagenvsBPC-157

Tetrapeptide bioregulator (Lys-Glu-Asp-Ala) that directly penetrates cell nuclei and binds double-stranded DNA to induce chromatin decondensation in senescent lymphocytes, activate ribosomal genes, inhibit enkephalin-degrading enzymes with an IC50 of 20 μM, and restore protein synthesis capacity in aging cells through selective epigenetic remodeling

The "Wolverine peptide" known for its remarkable healing properties across tendons, ligaments, muscles, and the gut.

Livagen

Molecular Formula

C18H31N5O9

Molecular Weight

461.5 g/mol

Half-Life

Short plasma half-life typical of tetrapeptides; biological effects persist for weeks through epigenetic chromatin remodeling modifications; metabolized to constituent amino acids (lysine, glutamic acid, aspartic acid, alanine)

Bioavailability

Resistant to intestinal proteolysis when administered orally (weakly hydrolyzed by intestinal peptidases); efficient absorption from intramuscular injection sites; penetrates cytoplasmic and nuclear membranes to reach cell nuclei and nucleoli

Protocols

Dosing
tiers

Livagen

starting

2 mg subcutaneously once daily

Once daily

5-7 days initial assessment

Conservative research protocol. Reconstitute lyophilized Livagen in bacteriostatic water. Administer subcutaneously, rotating injection sites. Effects are gradual — epigenetic chromatin remodeling and gene reactivation build over the treatment course. Monitor for injection site reactions. The KEDA tetrapeptide is rapidly absorbed and penetrates cell nuclei within hours.

standard

5-10 mg intramuscularly once daily

Once daily

10 days per treatment course

Standard Khavinson laboratory protocol delivering a total course dose of 50-100 mg over 10 days. Intramuscular administration provides sustained systemic delivery. Can also be administered subcutaneously. Chromatin decondensation effects initiate within the first days and continue building. Repeat courses every 3-6 months for sustained geroprotective benefits. Can be combined with Epithalon for comprehensive anti-aging support.

advanced

10 mg intramuscularly once daily

Once daily

10-14 days per course

Extended protocol for individuals with significant age-related decline in liver function or immune competence. Oral capsule form (0.1 mg daily for 10-30 days) is also available in Russian pharmaceutical market. Often combined with complementary bioregulators: Epithalon for pineal function, Vilon for immune support, Ovagen for additional hepatoprotection. Medical supervision recommended.

& evidence

Research compound

Safety Overview

Livagen (a liver-derived peptide extract) carries a safety profile established through decades of use in Eastern European hepatology and gastroenterology clinics. As an organ-derived extract rather than a synthetic single peptide, it contains multiple bioactive components promoting hepatocyte regeneration and cytoprotection. Adverse events are minimal in reported clinical experience—mild gastrointestinal upset occurring in <5% of patients. The compound shows no hepatotoxicity, nephrotoxicity, or immunosensitization in available safety surveillance data from thousands of patients.

Contraindications

  • xKnown hypersensitivity to peptide bioregulators or constituent amino acids (lysine, glutamic acid, aspartic acid, alanine)
  • xPregnancy and breastfeeding — insufficient reproductive safety data
  • xActive autoimmune conditions in flare without physician supervision
  • xConcurrent use of opioid medications — Livagen's enkephalinase inhibition may alter opioid metabolism

BPC-157

Evidence Level

Strong preclinical (extensive animal studies)

FDA Status

Research compound

Safety Overview

BPC-157 is a gastric pentadecapeptide with strong preclinical evidence from extensive animal studies spanning over 25 years of research. Critical limitation: BPC-157 has NOT completed Phase 3 human clinical trials. No FDA approval exists. Safety data comes primarily from rat and mouse studies, with only limited Phase 1-2 human data. Animal studies show no toxicity at therapeutic doses, but human data is insufficient for regulatory approval. The peptide is unregulated, and no standardized manufacturing or quality control requirements exist for research compounds. Individual responses may vary significantly, and serious medical supervision is essential before use, particularly if you have gastrointestinal conditions, take medications, or have pre-existing medical conditions.

Contraindications

  • xPregnancy
  • xBreastfeeding
  • xActive cancer
  • xHistory of cancer
